Answer:

0.51 %

Explanation:

Calculated value of the amount of oxygen is 3.9 g

Theoretical value of amount of oxygen is 3.92 g

We need to find the percent error in this experiment. It is given by the difference in theoretical and Calculated value divided by theoretical and multiplying it by 100. So,

E=\dfrac{3.92-3.9}{3.92}\times 100\\\\E=0.51\%

So, the percentage error is 0.51 %.

A diver is on a board 1.80 m above
Virty [35]

Answer:

v = 6.95 m/s

Explanation:

Given that,

A diver is on a board 1.80 m above  the water, s = 1.8 m

The initial speed of the diver, u = 3.62 m/s

Let v is the speed with which she hit the water. It will move under the action of gravity. Using the equation of motion as follows :

v^2-u^2=2gs\\\\v=\sqrt{u^2+2gs} \\\\v=\sqrt{(3.62)^2+2(9.8)(1.8)} \\\\v=6.95\ m/s

So, she will hit the water with a speed of 6.95 m/s.
